-maxVRAM= does not work

I tried using this "-maxVRAM=" startup parameter today and found it doesn't work. For example if I use "-maxVRAM=512" MSI Afterburner still shows that memory usage goes up to my max, 1024, with Video Memory on Default. It also doesn't work with Video Memory on Very High or any other lower setting.

Did you try it with video memory at default (video options) in combination?

Yes, I tested Video Memory on Very High, Normal, Low, and Default. I varied some other graphical settings too just to see if they were causing this for whatever reason.

Did you measure also performance along the way? It may very well be that its broken as others didn't have much success.

However it might be done in a way that you can rely on the MSI afterburner output?

I didn't take performance numbers but here's what I did get:

Video Memory Setting | Memory Usage Max in Afterburner

Without the parameter:

Video Memory Default = 1024

Video Memory Very High = 788

Video Memory Normal = 635

With:

Video Memory Default + -maxVRAM=512 = 1024

Video Memory Very High + -maxVRAM=256 = 788

Video Memory Normal + -maxVRAM=256 = 635

So MSI Afterburner does seem reliable. Even though I didn't get the frames per second I can say Default + -maxVRAM=256 didn't feel any less smooth than without the parameter.
